Justification / Modifications:
Mesmerize is taken at level 1 because you need the skill in your arsenal throughout the game, and Heartache costs so much, and does such little damage at rank 1, that it is virtually never worth using at that stage. Heartache is then taken at every available level, as it is your main way to stay in your lane and deal damage to your opponent. Smitten is not taken till the 12-15 range, because it's not until later on that Physical Carries become relevant, and shutting them down becomes important.
Because Mesmerize is not really being used to shut down at this point, it is more important (and even preferential) to have it at Rank 1 (4 Seconds) at this stage in the game, so maxing it out is not a priority. Also 1 extra second is not really worth giving up +2 Strength, +2 Agility and +2 Intelligence at this point in the game. It is maxed out later when it reaches the point where you want the target locked out for absolutely as long as possible; but this can be earlier than level 17 depending on your game.
As mentioned before, your skill build can vary as much as necessary. Smitten can be skipped entirely, Mesmerize can be maxed out sooner if you need some serious disables in the team, etc.

Lane Starting Items:
Runes of the Blight, 2x Mana Potion, 2x Mark of the Novice, 2x Minor Totem

Core:
Bottle >> Marchers >> 2x Talisman of the Exile >> Ghost Marchers >> Portal Key

Yes you are reading correctly, I don't only recommend Portal Key on Succubus; I consider it core. You need to have played her with Portal Key to realize the full spectrum of usefulness of this item on her. Her ability to jump in and completely take out two enemies make her a decent initiator even for teamfights and probably one of the best initiators for ganks. Portal Key also makes her an even more amazing chaser hero. She can blink after fleeing enemies and mesmerize them until her allies arrive.

After Core:
Wards of Sight >> Kuldra's Sheepstick >> Puzzle Box >> Shrunken Head >> Null Stone

Keep Warding, it's your number one priority. In most games Sheepstick will be the next item for an additional disable. Puzzle Box has good synergy with your Skills (Mesmerize, get out minions, Hold, Manaburn, beat down with minions and finish with Heartache brings down most enemies 1on1). Shrunken to make sure you get your CC's off.

DO NOT GET STAFF OF THE MASTER ON SUCCUBUS. EVER. PLEASE!
If you really want more damage during your ulti get Puzzle Box, it does WAY more damage and has so many other uses too.

Information:
Roles: Ganker, Babysitter, Nuker, Disabler, Ward Hoe
Prefered Lane: Any
Difficulty: 3 - Medium
Farming capabilities: 2 - Weak
Item dependancy: 1 - Very Low
Power:
- Early Game / Lane Control: 5 - Very strong (Very potent ult)
- Mid Game / Ganks: 5 - Very strong (High ganking power with her disables, nukes do good damage)
- Late Game / Team Fights: 3 - Medium (Disables still useful, if she survives)

30-Seconds-Guide:
- Early on with Succubus, you are a ganker, that is your role. After level 6 use Homecoming Stones and move around behind the trees to setup kills.
- Not all Heroes (even not all physical carries) suffer the same from smitten. Its mostly the heroes that go for stats instead of pure damage. Here a list of heroes that suffer greatly from the spell and are your number one priority: The Dark Lady, The Madman, Arachna, Puppet Master, Hammerstorm, Maliken, Pestilence, Pandamonium, Nighthound.
- Silence is really strong versus you. If they have silencers use your Portal Key to blink into fights and mesmerize the silencer as your first action to allow you to get your other CC's off at the start.
- Remember to keep wards up.
